MDEV-6041: ORDER BY+subqueries: subquery_table.key=outer_table.col is not recongized as binding
- Make JOIN::const_key_parts include keyparts for which
the WHERE clause has an equality in form
"t.key_part=reference_outside_this_select"
- This allows to avoid filesort'ing in some cases (and also
avoid a difficult choice between using filesort or using an index)
